      neat! I knew a lot of birds are tetrachromats, but I didn't know some people are too

        mantis shrimp are cool

        The species Gonodactylus smithii is the only organism known to simultaneously detect the four linear and two circular polarisation components required to measure all four Stokes parameters, which yield a full description of polarisation. It is thus believed to have optimal polarisation vision. It is the only animal known to have dynamic polarisation vision. This is achieved by rotational eye movements to maximise the polarisation contrast between the object in focus and its background.

          Mantis Shrimp can also punch so fast that it causes sonoluminescence which is the emission of light from imploding bubbles in a liquid when excited by sound.

      assuming the extra cone type adds one more independent color dimension for her, that makes her a tetrachromat overall.

      Assuming? We can't even get a cool claim "yeah I can see the shiny dimension of things"

      Tetrachromacy may also enhance vision in dim lighting, or in looking at a screen.

      This sucks
